QUESTION 151 Which device is needed to integrate H.320 into the Cisco video solution?

A. video gateway B. MGCP gateway C. H.323 gatekeeper D. MCU

Answer: C Explanation: As with H.323 MCUs, H.320 gateways are provisioned in Cisco Unified CallManager as H.323 gateways, and then route patterns are configured to extend calls to these devices.

QUESTION 152 The following exhibit shows configs for H.323 gateway. You have been asked to implement TEHO from a remote branch office with area code 301 to the HQ office with area code 201 using Cisco Unified Communications Manager. The remote office has an MGCP gateway and the HQ office has an H.323 gateway. Once the call arrives at the HQ, it should break out to the PSTN as a seven-digit local call. Which statement about the route pattern is true?

A. route pattern should be 91201.[2-9]XXXXXX with Discard Digit as Predot and Prefix 9 B. route pattern should be 91201.[2-9]XXXXXX with Discard Digit as Predot C. route pattern should be 91201.[2-9]XXXXXX D. route pattern should be 9.1201[2-9]XXXXXX with Discard Digit as Predot E. route pattern should be 9.1201[2-9]XXXXXX with Discard Digit as Predot and Prefix 9

Answer: A

QUESTION 153 Which two statements about the functionality of a gatekeeper are true? (Choose two.)

QUESTION 155 Which statement about the function of a gatekeeper is true?

A. A gatekeeper improves call routing between servers within a single Cisco Unified Communications Manager cluster. B. A gatekeeper can replace the dial plan of a Cisco Unified Communications Manager cluster. C. A gatekeeper can simplify the dial plan between many different Cisco Unified Communications Manager clusters. D. Gatekeepers can be implemented to deploy RSVP-based CAC.

Answer: C

QUESTION 156 For which VoIP protocol does a gatekeeper provide address translation and control access?

QUESTION 159 Which statement about technology implementation strategy is true?

A. Cisco Unified Communications Manager Express can be configured to function with no Cisco Unified Communications Manager cluster in the enterprise. B. Cisco Unified Communications Manager Express in SRST mode can be configured to function with no Cisco Unified Communications Manager cluster in the enterprise. C. SRST can be configured to function with no Cisco Unified Communications Manager cluster in the enterprise. D. SRST and MGCP fallback can be configured to function with no Cisco Unified Communications Manager cluster in the enterprise.

Answer: A

QUESTION 160 What command is used to map internal extensions to the corresponding E.164 PSTN number when using Cisco Unified Communications Manager Express in SRST mode?

A. CAPF enrollment supports the use of authentication strings. B. The CAPF itself has to enroll with the Cisco CTL client. C. LSCs are issued by the Cisco CTL client or by the CAPF. D. MICs are issued by the CAPF itself or by an external CA.

Answer: A

QUESTION 162 An update of the configuration using the Cisco CTL client not needed when _______.

A. a Cisco Unified CallManager has been removed B. an LSC of the IP phone is upgraded C. a security token is added to the system D. an IP address of the Cisco TFTP server has been changed

Answer: B

QUESTION 163 Which statement is not true about GARP?

A. GARP attacks require access to the target LAN or VLAN. B. GARP can be used for a man-in-the-middle attack. C. GARP is normally used for HSRP. D. GARP can be disabled at Cisco IP phones.

Answer: CD Explanation: You must also add the application users or the end users to the Standard CTI Secure Connection user group in Cisco Unified Communications Manager Administration to enable TLS for the application. After you add the user to this group and install the certificate, the application ensures that the user connects via the TLS port.

QUESTION 165 Which two statements about symmetric encryption are true? (Choose two.)

Answer: AC Explanation: There are two basic techniques for encrypting information: symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption.) in symmetric key As long as both sender and recipient know the secret key, they can encrypt and decrypt all messages that use this key. A public key is made freely available to anyone who might want to send you a message. A second, private key is kept secret, so that only you know it.

QUESTION 166 Refer to the exhibit. Locations-based CAC has been configured between HQ and the BR site. Assume that the priority queue has been provisioned correctly for three G.729 calls. What happens when the fourth call is placed from HO to BR?

A. The call will get through via the WAN. but it will experience poor audio quality. B. The call will fail. C. The call will be queued until one of the existing calls drop. D. The call will get through without any issues.

Answer: B

QUESTION 167 Video calls using 384 kbps need to be supported across a gatekeeper-controlled trunk. What value should be entered into the gatekeeper to support this bandwidth?

A. 768 kbps B. 384 kbps C. 512 kbps D. 192 kbps

Answer: B Explanation: A 384-kb/s video call may comprise G.711 at 64 kb/s (for audio) plus 320 kb/s (for video). This sum does not include overhead. If the audio codec for a video call is G.729 (at 24 kb/s), the video rate increases to maintain a total bandwidth of 384 kb/s.

Answer: B Explanation: Call Forward Unregistered (CFUR) functionality provides the automated rerouting of calls through the PSTN when an endpoint is considered unregistered due to a remote WAN link failure.

QUESTION 170 While operating in SRST, what is needed to route calls outside of the remote site location to the PSTN?

Answer: BE Explanation: IP Phone display and Physical phone IP settings are two locations were an end user can determine if an IP phone is working in SRST mode.

QUESTION 174 What is the fastest way for an engineer to test the implementation of SRST in a production environment?

A. Shut down the Cisco Unified Communications Manager Servers. B. Shut down the switch ports connected to the Cisco Unified Communications Manager Servers. C. Add a null route to the publisher Cisco Unified Communications Manager at the remote router. Remove the null route when the operation is verified. D. Unplug the IP phones from their switch ports. E. Verification is not needed.
